Abstract

L'invention concerne un appareil de traitement d'images permettant d'acquérir des images tomographiques OCT qui peuvent être capturées par un appareil d'imagerie OCT conçu pour scanner une cible à capturer à l'aide d'une lumière de faible cohérence le long d'une ligne de balayage principale prédéfinie. L'appareil de traitement d'images comprend une unité d'acquisition d'images conçue pour acquérir plusieurs images tomographiques OCT de la cible à capturer le long de plusieurs lignes de balayage principales qui présentent des directions différentes, et une unité de commande d'affichage conçue pour afficher les images tomographiques OCT sur un écran d'affichage en utilisant une présentation qui permet de montrer les différences de direction de chaque ligne de balayage principale de manière à refléter une relation relative entre les directions respectives des lignes de balayage principales par rapport à la cible à capturer dans des images tomographiques OCT correspondantes.
